. FAs'rENTNG MEANS.

Application ld April 21; 1924.. SerialNq.' 207,979.

My invention relates to fastening means, .the device of my invention being especially useful in fastening closures upon steel barrels and the like, but the 'invention is not to be thus limited. v

My invention vcomprlses a sheet member, such as a barrel closure, whlch 1s formed with an opening therethrough and which isangularly continued at said opening to form a socket, and a bolt passing vthrough said socket,'the bolt and socket having engaging portions at unequal distances from the axis of the bolt to prevent lthe bolt from turning,-

saidl bolt having two enlargements between which said socket is confined.

In the drawing, A Fig. 1 is a'fragmentary view of the end of a steel barrel, embodying the invent-ion, Figs. 2, 3 and 4 are substantially full size views 'of portions of theclsing means illustrated in Fig. 1. -The numeral 1 denotes a steel barrel'in which a head 2, formed of a sheet of metal, is suitably fastened. In this head is cut an orifice closed by-a circular cover or lclosure 3 made with an annular flange 4. In

' the head 2 is fastened a plurality of threaded studs 5, which extend through perforations in the annular flange 4, and upon which I 30 .are mountedsuitable nuts 6. An annular tions of which are extruded or continuedv angularly to the sheet member 2 to form a square socket 10 of a size to .fit the square shank or stem'portion- 11 of the holt 5: The

engaging portions of' the socket l0 and boltshank are thus at unequal distances from the axis of the bolt so that the bolt is held from turning. In the annular space within the depression 8 is placed a circular 'disc or i'i'ng 12, and this disc or`ring is made with :1-

square central opening which fits snugly around the squareocket 10. IVhen the bolt has been ptit in place, in the. first instance, the' parts are taken to a punching machine pr'ovided withfa tubular punch -the perforation. of which tits the threadedl portion of the bolt., This punch is caused to surround.

and 'descend along. said threaded portion until 'it reaches the enlarged square shank 11, and as it then continues to descend it cuts this oversize portion away from the bolt and squashes it down upon the disc 12, produc-ing a Hange or enlargement substantialhlasjindicated at 12 in Fig. 2, this flange co-' o erating with thebolt header enlargement `in locking the bolt tightly in position, the

socket 10 and ring 12 being conlined between the bolt enlargement 5', 12.-v The ring 12 sufficiently fits the wall 8, of member 2, that surrounds the socket 10, as well as sufiil ciently fitting the socket so that the proper angularity of the socket to the body of the sheet member 2 is not disturbed .when theange 12' is swaged. It is obvious that the socket and bolt may beotherwise shaped to provide enga ingportions at unequalv disf tances from t ie. b'olt axis to prevent the boltv from turning.

To those versed in the artit is known that bolts are used in steel barrels for the-purpose specified, and it` is also known what .difficulties usually are encountered intconneet-ion with such structures. These difficulties I overcome bymeans of `my improved device, as I shall now point out.l It is no- Aticed, 'and has hereinbefore been stated, ,that

the disc 12 fits tightly around the protruding edges 10 of the square bolt perforations. Let it be assumed that thisdisc is omitted,

let the bolt be placed in position, and let the enlarged 'square portionof the bolt be rolled down upon lthis projecting 'socket l0. It will be found that the walls ofthe socket are in danger-of spreading and crumbling under the pressure of the descending metal with the result that the .bolt-` while sufiic-iently tied to the barrel. may not be sccurely` held circumferentially. and that it lnay'work loose enough toturn when the nut is screwed-into place or unscrewed. Furthermorethe bolt maybe set ,at an angle, d ne to the aforesaid spreading and crumbling of the socket,making it. more difiicult to set the cover, or barrel Ihead. in place on the bolts, when they are more or less out of line with the holes in the cover and gasket.

Now,- it is noticed that the disc fits tightly. l

aroundA the edges 10, that itis substantially 'as thick as the projected height of said edges,

and that it dis large enough in diameter to support the said edges against spreading and crumbling. ,As a'consequence the bolt is -solidly7 and squarely set, and the metal of-l the barrel head 2 is reinforced by the disc,

' lso that `a permanent and reliable structure is provided.

I claim:

l. The combination with a sheet member formed with anvopening therethrough and angularly continued at said opening to form a socket and having a Wall portion surrounding and spaced from said socket; of a bolt passing through said socket, the bolt and socket having engaging portions at unequal Adistances from the axisv of the bolt to prevent the bolt from turning; and a ring sur# rounding said socket and surrounded b vsaid Wall portion and fitting said socket and Wall portion, said bolt having two enlargements lbetween which said socket and ring are conportions at unequal distances from the axis of the bolt to prevent the bolt from turning;-

said bolt having two enlargements between which said socket is confined.
